Aetiology, incidence and morphology of the C‐shaped root canal system and its impact on clinical endodontics

The C-shaped root canal constitutes an unusual root morphology that can be found primarily in mandibular second permanent molars. Due to the complexity of their structure, C-shaped root canal systems may complicate endodontic interventions. A thorough understanding of root canal morphology is therefore imperative for proper diagnosis and successful treatment. This review aims to summarize current knowledge regarding C-shaped roots and root canals, from basic morphology to advanced endodontic procedures. To this end, a systematic search was conducted using the MEDLINE, BIOSIS, Cochrane Library, EMBASE, Google Scholar, Web of Science, PLoS and BioMed Central databases, and many rarely cited articles were included. Furthermore, four interactive 3D models of extracted teeth are introduced that will allow for a better understanding of the complex C-shaped root canal morphology. In addition, the present publication includes an embedded best-practice video showing an exemplary root canal procedure on a tooth with a pronounced C-shaped root canal. The survey of this unusual structure concludes with a number of suggestions concerning future research efforts.

“…Com relação ao uso do sistema ultrassônico na etapa de obturação, Moreno 19 e Agarwal et al 7 também verificaram ótimos resultados com este sistema em relação a outras técnicas testadas. 20 , um subproduto gerado com o acionamento da ponta ultrassônica é a energia térmica. Quando a energia de calor é transmitida para o espaçador, o calor produzido é capaz de amolecer a guta-percha.…”

Introdução: O preenchimento com material endodôntico obturador em dentes com reabsorção radicular interna é extremamente difícil. Objetivo: Avaliar a eficácia de duas técnicas de obturação no preenchimento de cavidades experimentais de reabsorção interna. Material e método: Vinte incisivos centrais superiores artificiais, com a presença de uma cavidade simulada padronizada de reabsorção no terço médio do canal radicular, foram utilizados. Após o preparo endodôntico dos dentes, os mesmos foram randomicamente divididos em dois grupos (n=10), de acordo com a técnica de obturação empregada: híbrida de Tagger ou com auxílio do sistema ultrassônico. A verificação da obturação endodôntica, junto à cavidade de reabsorção interna, foi feita por meio da tomada radiográfica com dois tipos de incidência: mesiodistal e vestibulolingual. Para a análise da área de obturação, foi empregado o programa Image Tool®. Os dados obtidos da obturação foram submetidos à análise estatística por meio do Teste t de Student, com nível de significância de 5%. Resultado: Não houve diferença estatística entre as técnicas de obturação testadas. Apenas pôde-se observar diferença significativa nos dentes obturados com auxílio do ultrassom, quando se comparou a incidência radiográfica realizada no sentido mesiodistal com a vestibulolingual. Conclusão: As duas técnicas de obturação testadas foram similares no preenchimento da cavidade de reabsorção interna.

SummaryInstrument separation during endodontic therapy is a frequent accident with rotary instruments being more likely to separate than manual ones. The treatment of cases with a separated instrument can be either conservative or surgical. A conservative approach involves the following treatment choices: a) bypass of the fragment, b) removal of the fragment, c) instrumentation and obturation coronally to the fragment. Concerning the removal of a separated instrument, a variety of techniques and systems have been developed. Ultrasonics, in combination with the operative microscope constitute the most effective and reliable tools for removing a separated endodontic instrument from a root canal. The likelihood of successful removal depends on: the level of separation (coronal, middle or apical third); location in relation to the root canal curvature; the type of separated instrument; its length; the degree of canal curvature and the tooth type. Several complications may occur during the management of a separated instrument: separation of the ultrasonic tip or file used for bypassing or removing the instrument; further separation of the fragment; perforation; ledge; extrusion of the file into periapical tissues; tooth weakening due to dentin removal, as well as excessive temperature rise in periodontal tissues. Prognosis for a tooth retaining a separated instrument depends on the presence of a periapical lesion, the microbial load of the root canal during the time of separation and the quality of the obturation.
